Heavy traffic has built up at Mlolongo after police mounted roadblocks restricting movement into Nairobi’s Central Business District ahead of the June 25 Gen Z anniversary protests.

Motorists and commuters faced long delays along Mombasa Road as police intensified security checks at Mlolongo, Athi River and other entry points leading into Nairobi.

The operation formed part of a wider security deployment across the capital on Thursday, June 25, 2026, as authorities sought to control access to the CBD during demonstrations marking the second anniversary of the June 25, 2024 anti-Finance Bill protests.

By early morning, traffic had stretched across sections of Mombasa Road, with matatus, buses and private vehicles moving slowly as officers stopped vehicles for inspections.

Several commuters were stranded after some public service vehicles avoided entering the city centre altogether.

Police also mounted roadblocks along Thika Road, Jogoo Road, Lang’ata Road and Waiyaki Way as security agencies tightened surveillance around Nairobi.

At Githurai and Allsops, officers blocked several vehicles from accessing the CBD, causing heavy congestion and delays.

Some passengers were forced to walk long distances or seek alternative transport after matatus suspended trips into town.

Long-distance bus operators also reported disruptions, with some companies delaying or cancelling travel to Nairobi due to security concerns.

The heightened police presence comes as Kenyans mark the June 25 anniversary protests that shook the country in 2024.

Memories of 2024 protests

In 2024, hundreds of Gen Z protesters stormed Parliament during demonstrations against the Finance Bill 2024 after lawmakers passed the controversial tax proposals.

The protests forced President William Ruto to withdraw the bill following nationwide outrage over the rising cost of living and proposed taxes.

This year, youth groups and activists have organised marches, vigils and memorial events to honour those killed during the protests and demand accountability over police brutality and alleged human rights abuses.

Authorities insist the security measures are aimed at maintaining public order and protecting critical infrastructure.

Interior Cabinet Secretary Kipchumba Murkomen said Wednesday would remain a normal working day despite the planned demonstrations.

“Tomorrow is a normal working and school day. However, the police received a notification from some citizens who would like to engage in a public demonstration,” Murkomen said.

He added that police would protect peaceful protesters but warned against violence, destruction and criminal activity.

Despite the assurances, tension remained high across Nairobi on Thursday morning as businesses stayed closed in some parts of the CBD and traffic congestion spread across major highways leading into the capital.
